Katherine Heigl is getting raves for the slinky red gown she wore to the premier of her new film, “One For The Money,” last night. What with that crimson color, you could be forgiven for assuming the dress was Valentino.

Instead, the body-hugging dress was from a French couturier who can’t design under his own famous name. The label is Herve L. Leroux. But the designer’s real name is Herve Leger – the master of couture draping who invented the Bandage Dress in 1989. That sexy skintight mummy confection, since being re-released by current brand owner Max Azria, has become ubiquitous at proms each spring.

Mr. Leger, after losing control of his company and eponymous brand in 1999, opened a shop on Paris’ Rue Jacob a year later and began designing under a label created as a reference to his red hair: le roux – get it? He still specializes in dresses that look graceful yet molded to the body – and does both made-to-measure couture, and ready to wear.

Ms. Heigl look smashing with all her curves on display – exuding Marilyn or Marlena like Hollywood royalty.
